Concept of On-Site Electro Chlorination
Electro chlorination is an electrolysis process where natural seawater or a brine solution (fresh water + salt) is converted into sodium hypochlorite. This process provides an efficient and safe method for chlorine production on-site.
When DC (Direct Current) passes through titanium electrodes in a saline solution, the following reactions occur:
- ➤ Electrolysis in an undivided cell using DC power in a saline solution.
- ➤ Anode: Chloride ions are oxidized to chlorine gas (Cl2).
- ➤ Cathode: Water is reduced to form sodium hydroxide (NaOH) and hydrogen (H2).
- ➤ Chlorine reacts with sodium hydroxide to produce sodium hypochlorite (NaOCl).
🧪 Overall Reaction:
2NaCl (salt) + H2O (water) → NaOCl (hypo) + NaCl (salt) + H2 (hydrogen)
- ➤ Produce Cl2 in the form of sodium hypochlorite.
